GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 652,177,

Application filed September 7, 1899 $erial No. 729,685. (No model) Toall whom it may concern:

Be it known that I, HENRY F. GABEL, of Pittsburg, in the county ofAllegheny and State of Pennsylvania,-have invented a new and usefulImprovement in Gas-Burners, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, in which Figure 1 is a verticalcentral section of my improved burner; and Fig. 2 is a plan view, partlybroken away, showing the perforated diaphragm.

My invention relates to gas-burners, and is designed to prevent flashingback of the flame, which causes burning of the gas in the mixer.

In the drawings, 2 represents the tubular stem of a burner, the lowerpart3 of which forms the mixer. The upper part 4 is swelled outwardly toform a chamber 5 and is preferably provided on opposite sides with slots6 and recesses beneath and registering therewith. Upon the flat top ofthe burner-stem rests a partition or diaphragm 7, which is formed of No.0 perforated metal, and this is secured in place by the ring 8, whichfits upon its edge portion and is provided with a depending annularflange 9, which fits closely about the edge of the chamber 5. This ringis secured by screw-bolts 10, which extend through the ring and theslots in the sides of the chamber 5 and are secured by the nuts at theirlower ends. These screw-bolts also serve to secure the burner-cap 11 inplace, this cap resting upon opposite lugs 12, projecting from the fiatupper face of the ring and having slots which are engaged by thescrewbolts, the heads of the bolts lying in suitable recessessurrounding the slots. The lower face of the edge portion of theburner-cap is made flat and parallel with the fiat upper face of thering.

In the use of the device the mixture of gas and air passing up throughthe perforated partition burns in an annular flame projectdated June 19, 1 900.

ing outwardly from between the burner-cap and the ring 8, and flashingback of the mixture is prevented by the diaphragm and by the tight jointaround its edges, which prea tight joint is absolutely necessary toobtain 5 5 the desired result; also, that No. 0 perforated metal is mostdesirable, as larger-sized perforations will allowa flashing back, whilesmaller-sized ones choke the How of the mixture and prevent properaction. isterin g faces between the bu rner -cap and the clamping-ringare also very desirable in preventing flame passing back into thechamber above the diaphragm and in giving an even flame.

The advantages of my invention result from the preventing of theflashing back into the mixer, which is always liable to occur withordinary burners and also from the simplicity and cheapness of theburner, which is of few parts and these held together by the single pairof screw-bolts. The clampingring may be made integral with the cap andits lugs, and many other changes may be made in the shape andarrangement of the burner, clamping-ring, and the other parts withoutdeparting from my invention, since I claim- 1. In a gas-burner, aburner-stem termi nating in an enlarged burner-chamber, a cap entirelycovering the said chamber, a lower ring with spacing-lugs between it andthe cap, the said ring having a flanged connection with theburner-chamber, and a perforated partition clamped between the ring andthe chamber; substantially as described.

2. In a gas-burner, a tubular burner-stem terminating in an enlargedburner-chamber, a conical cap entirely covering the chamber, aclamping-ring with spacing-lugs between it and the cap, said ring havingmeans for securburner stem with a flanged coning it to the Flat reg 6onection, and a substantially-horizontal perforated partition clampedbetween the ring and the burner; substantially as described.

3. A burner stem having an enlarged chamber at its upper end, aperforated diaphragm seated thereon, a clamping-ring resting on thepartition and having a depending flange surrounding the edge portion ofthe chamber, spacing-lugs on the top of the ring,
